Anomaly Analysis

Fraud Detection Through Anomalies

Project Overview

This project focuses on detecting fraudulent transactions using machine learning models and anomaly detection techniques. Given the extreme class imbalance, the main objective is to enhance fraud detection while minimizing false negatives, ensuring high recall without compromising precision.
Github

Implemented Techniques

• Logistic Regression:
Initial model without adjustments, achieving high accuracy but poor fraud detection.

Anomaly Detection Approaches

• Minimum Covariance Determinant (MCD): Identifies outliers based on robust covariance estimation.
‍• Isolation Forest: Detects anomalies by analyzing data point isolation in the feature space.

Class Balancing Strategies

• Undersampling: Reduces majority class to balance distribution.
‍• Oversampling: Increases fraud cases to prevent model bias.
‍• SMOTE (Synthetic Minority Over-sampling Technique): Generates synthetic fraud samples to improve representation.
‍

Key Considerations

‍The main challenge in fraud detection lies in handling skewed distributions, where fraudulent transactions constitute less than 0.2% of the dataset. Traditional classifiers struggle in such scenarios, making precision-recall trade-offs crucial. Anomaly detection methods leverage the inherent rarity of fraud cases, while data balancing techniques prevent models from being biased toward the majority class.

Ensemble Models

Machine Learning

Project Overview

This project implements and compares different machine learning models based on Ensemble Methods to predict a store's sales. It analyzes two main techniques: Bagging and Boosting, which improve prediction accuracy by combining multiple models. To evaluate which method performs better, we use Mean Squared Error (MSE), a metric that measures how close our predictions are to the actual sales.

Genetic Algorithms

Artificial Intelligence Programming

Project Overview

In this project, we will develop a Genetic Algorithm (GA), an optimization technique inspired by the principles of natural selection, to design the most optimal menu for a restaurant. The GA will be programmed to assess various menu options based on multiple criteria, including nutritional value, preparation cost, and taste preferences.

Modular

Platform with Augmented Reality

Project Overview

modulAR is a multi-service platform for creatives and artists, allowing them to offer services, market their works, search for jobs, and present their projects using Augmented Reality.

The hypothesis behind the creation of modulAR is based on the idea that Augmented Reality can significantly raise sales and the public’s interaction with creatives and their products.
